Ganymede's Salty Surface Reveals Organics, Confirms NASA

NASA's Juno spacecraft has discovered mineral salts and organic compounds on Jupiter's moon Ganymede, providing insights into the moon's origin and composition. The data suggests the presence of a deep ocean brine that reached the moon's surface. Ganymede, the largest moon in the solar system, has a magnetic field and an underground sea beneath its icy shell. The findings could aid in understanding other distant moons and dwarf planets in the solar system and beyond.

"James Webb Space Telescope Unveils Stunning Images of Saturn's Changing Seasons"

The James Webb Space Telescope has captured stunning new images of Saturn, providing insights into the planet's seasonal changes as summer transitions into fall in its northern hemisphere. The infrared images reveal a cooling trend and the reversal of air flows, indicating the approaching autumnal equinox. The data collected by Webb's MIRI instrument allows scientists to measure temperatures, gases, chemicals, and clouds at various levels of Saturn's atmosphere. These early results highlight the potential of the Webb Telescope in the field of planetary astronomy, offering a glimpse into previously inaccessible wavelengths of light and paving the way for future discoveries.
